attempt to remove them forcibly, as this will damage

them.

Note

• The Auto Standby function turns the subwoofer on when the

input signal exceeds a certain level. If the Auto Standby function

does not work reliably, try slightly increasing or decreasing the

subwoofer output level on your receiver.

Using the Rubber Stoppers for a More Stable

Platform

We recommend using the supplied rubber stoppers to

achieve the best possible sound from your speakers. The

rubber stoppers prevent the speakers from moving,

providing a more stable platform. Use rubber stoppers for

the center speaker.

Using the Floor Pads for Subwoofer

If the subwoofer is placed on a hard floor (wood, vinyl,

tile, etc.) and playback is very loud, the subwoofer’s feet

may damage the flooring. To prevent this, place the

supplied pads underneath the subwoofer’s feet. The pads

also provide a stable base for the subwoofer.

Setting the Subwoofer Level

To set the level of the subwoofer, use the

OUTPUT LEVEL control. Set it so that bass

sounds are evenly balanced with the treble sounds

from the other speakers. Because our ears are less

sensitive to very low bass sounds, there’s a temptation to

set the level of the subwoofer too high. As a rule of thumb,

set the subwoofer level to what you think is the optimal

level, and then back it off slightly.

Wall Mounting

To mount the front/surround speakers vertically, use the

keyhole slot shown to hang each speaker on a screw that’s

securely screwed into the wall.

To mount the center speaker horizontally, use the two

keyhole slots shown to hang the speaker on two screws that

are securely screwed into the wall.

Tip

• If the center speaker is tilted, loosen the screw on the declined

side to move upward so that the speaker could be adjusted

vertically.

Status indicator

Off: Subwoofer in standby mode or

disconnected from power source

Blue:Subwoofer on

The status indicator lights blue when

low frequency sound is being passed

through the speaker.

The indicator does not light in the

normal dialog or high frequency

sound.

Note

• The indicator does not indicate that

power supply of the subwoofer has

turned on.

With the Auto Standby function, the

SKW-658 automatically turns on

when an input signal is detected in

standby mode. When there’s no input

signal for a while, the SKW-658

automatically enters standby mode.

To AC outlet

OUTPUT LEVEL control

This control is used to adjust the

volume of the subwoofer.

LINE INPUT

This RCA input should be

connected to the subwoofer pre

out on your AV receiver with

supplied RCA cable.

Caution

• A mounting screw’s ability to support a

speaker depends on how well it’s

anchored to the wall. If you have

hollow walls, screw each mounting

screw into a stud. If there are no studs,

or the walls are solid, use suitable wall

anchors. Use screws with a head

diameter of 9 mm or less and a shank diameter of 4 mm

or less. With hollow walls, use a cable/pipe detector to

check for any power cables or water pipes before making

any holes.

• Leave a gap of between 5 mm and 10 mm between the

wall and the base of the screw head, as shown (We

recommend that you consult a home installation

professional).

The Home Theater means that you can enjoy surround

sound with a real sense of movement in your own home —

just like being in a movie theater or concert hall.

.

Speaker Connection Precautions

Read the following before connecting your speakers:

• Turn off your receiver before making any connections.

• Pay close attention to speaker wiring polarity.

Connect positive (+) terminals to only

positive (+) terminals, and negative (–)

terminals to only negative (–) terminals. If the

speakers are wired incorrectly, the sound will be out of

phase and will sound unnatural.

• Be careful not to short the positive and negative wires.

Doing so may damage your amp.

Enjoying Home Theater

Wall

5 to 10 mm

1 Front speakers (SKF-693)

They should be positioned facing the listener at about

ear level, and equally spaced from the TV. Angle

them inward slightly so as to create a triangle, with

the listener at the apex.

Height speakers

This speaker is type of integrated with the front

speakers and height speakers. The height speakers

designed with the top of the front speakers are facing

toward the ceiling to create an elevated audio effect

in the Dolby Atmos and Dolby Surround listening

modes by providing sounds echoing off the ceiling.

2 Center speaker (SKC-591N)

Position it close to your TV (preferably on top)

facing forward at about ear level, or at the same

height as the front left and right speakers.

3 Surround speakers (SKR-590)

Position them at the sides of the listener, or slightly

behind, about 60 to 100 cm above ear level. Ideally

they should be equally spaced from the listener.

4 Subwoofer (SKW-658)

The subwoofer handles the bass sounds of the LFE

(Low-Frequency Effects) channel and bass from the

satellite speakers when a crossover is specified. The

volume and quality of the bass output from your

subwoofer will depend on its position, the shape of

your listening room, and your listening position. In

general, a good bass sound can be obtained by

installing the subwoofer in a front corner, or at one-

third the way along the front wall, as shown.

without prior notice.

Note

For non-magnetic shielded speakers:

Try moving the speakers away from your TV or monitor. If

discoloration should occur, turn off your TV or monitor,

wait 15 to 30 minutes, and then turn it back on again. This

normally activates the degaussing function, which

neutralizes the magnetic field, thereby removing any

discoloration effects.
